Subject partial upgrade
Date Sun, 01 Oct 2017 01:03:07 GMT
Hi there,

So far, flink job is interpreted and deployed during bootstrap phase. Once
pipeline runs, it's very hard to do partial upgrade without stop execution.
(like savepoint is heavy) Is there any plan to allow upload annotated jar
package which hints which stream tasks implementation CAN BE partial
upgraded after next checkpoint succeed without worry about backfill.


Thanks,
Chen
